Mould and mould base accessories are the precision components that support ejection, alignment, side action, plate movement, cooling, sprue entry, identification, cycle monitoring and maintenance inside a mould assembly. We supply these parts as individual replacements, matched component sets and application-based packages for new moulds, repairs and preventive maintenance.

Our range covers mould ejection systems, ejector pins and sleeves, air vents, runner lock pins, spring cores, plate accelerators, ejector plates, sleeve pins, stop pins, locating rings, guide pins and bushes, oilless components, interlocks, block sets, dowel pins, slide retainers, mould latches, parting locks, date indicators, cooling products, sprue bushes, mould bases, mould sprays, counters and polishing tools.

A mould base is the main plate-and-guidance structure that carries the cavity, core, ejection and support system. Mould base accessories are the functional components fitted within or around that structure, such as guide elements, ejector parts, interlocks, retainers, cooling fittings and sprue bushes. We review both together because accessory dimensions must match the mould-base layout.

We begin with the moulded-part geometry, material, draft, shrinkage, surface requirements, likely sticking areas and available ejection space. We then review the number, type, diameter and position of ejectors, required stroke, plate movement and permissible witness marks. A part drawing and mould layout allow us to recommend the system more accurately.

Choose an ejector pin by checking available contact area, part shape, required ejection force, pin diameter, length, head style, operating temperature, material, hardness, surface treatment and permissible mark on the component. Standard round pins suit many applications, while blade, flat, stepped, air-assisted or coated pins address specific space, geometry or wear conditions.

A guide pin and bush must be selected as a matched guidance system. Confirm pin diameter, bush dimensions, installation fit, plate thickness, guiding length, expected side load, lubrication method, operating speed and required alignment accuracy. We also check whether the application needs standard guidance, ejector guidance, stripper guidance or a special low-maintenance arrangement.

A mould latch controls the opening or closing sequence between selected plates, commonly in multi-plate arrangements. A mould parting lock holds the parting line closed until the intended opening force or sequence occurs. The two can work in different parts of the same mould, so selection must follow the complete plate-motion diagram rather than the product name alone.

Start with the cooling-channel drawing, connection size, available depth, required flow, pressure, temperature, sealing method and access for maintenance. Baffles redirect flow inside drilled channels, plugs close or route passages, couplings connect external lines, and heat pipes transfer heat from difficult areas. Each item must match the complete cooling circuit.

Send the overall length, head diameter and thickness, outside diameter, bore or orifice, nozzle-seat radius, inlet details, runner-end form, mounting fit and required material or hardness. Also share the machine-nozzle specification and mould drawing. Small mismatches at the nozzle seat or bore can cause leakage, poor filling or difficult sprue release.

Send the product name or item code, dimensioned drawing, material, hardness, coating, surface finish, critical tolerances, mating-part details, application, operating temperature, quantity and delivery location. For an accessory package, include the mould layout and bill of materials. Clear information helps us quote price, feasibility and lead time without assumptions.
